NELS NELSON, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR OF ONE-HALF TO SAMUEL M. SMITH, OF SAME PLACE.

SLEEVE OR COLLAR BUTTON OR STUD;

SPECIFICATION forming part of Letters Patent No. 250,277, dated November 29, 1881.

Application filed September 1, 1881. (No model.)

To all whom it may concern Be it known that I, NELs NELSON, a subject of the Crown of Sweden,residin g at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Sleeve or Collar Buttons or Studs, of which the following is a specification.

My invention relates to that class of buttons and studs in which the shoeis hinged upon the post, so that it may be turned parallel with the same for insertion into a button-hole, and then turned at right angles to secure it in place.

The object of my invention is to provide a button or stud which shall be of cheap, simple, and durable construction and consist of few parts.

It consists of the novel hinge-joint formed by the union of the post with the back plate or lining of the shoe, and also of the novel construction of the back plate.

The details of construction and of the parts of myinvention are more full yillustrated in the accompanyingdrawings, reference to which is hereby made, and in which- Figure 1 is an elevation, showing the shoe tipped for insertion. Fig 2is a central section of the post and back plate in. the position indicated in Fig. 1. Fig.3is a plan of the back plate and locking-spring. Fig. 4 represents the post. Fig. 5 is a central section of the post and back plate when turned to retain the button in the garment.

The shoe is constructed, in the ordinary manner, of an outer disk, A, burnished or turned down upon a lining or back plate, A. This back plate, A, is provided with a slot or orifice, (indicated in Fig. 3 by the central dotted lines,) through which I pass the novel shaped post B, which is bent upon itself at a point near its end to form the foot I) b, as is indicated in Figs. 2, 4, and 5. The post B, which is preferably made of flat stock, is inserted through the orifice in the back plate until it assumes the position indicated in Fig. 5. I then place across said back plate aflat spring, 8, so as to engage the face I) of the post-foot. Then I burnish or otherwise secure the outer disk, A, onto the back plate, to form the shoe and confine the spring and post. The shoe A can then be turned upon the post to assume the position indicated in Figs. 1 and 2.

The back plate, engaging the bent portion of the post, as shown in Fig. 2, forms ahingejoint, upon which the shoe can be turned to assume at will either the position shown in Fig. l for inserting the button or in Fig. 5 for seouring it in the garment.

It will be observed that by this novel construction I secure without the use of lugs or journals a hinge-joint which is cheap, durable, and effective.

The locking-spring s engages the flattened faces I) and b of the post-foot and holds the shoe firmly in position, as may be desired, either at nearly a right angle to or parallel with the post B. The face I) is beveled slightly, so that when engaged by the spring 8 the shoe will press more firmly against the post B at the side a, to stiffen and brace the shoe when turned to secure it in the garment after insertion therein, the shoe then lying at a right angle to the post. That part of the shoe lying in front of the post at the point ais raised, so that when the shoe assumes the position shown in Fig. 5 it will secure the post at right angles to the shoe, and will further serve as a guide in inserting the shoe into the button-hole. That part of the post lying between the face I) and the notch I) forms a stop to prevent the post being pulled out of the back plate.

The head or top of the button 0 may be of any desired shape or ornamentation.

Having thus described my invention, what 1 claim therein as new, and desire to secure by Letters Patent, is-

1. In a, sleeve or collar button or stud, the post or shank B, bent upon itself at one end to form a foot, with beveled face b, fiat face b, and notch b as shown. 0

2. Inasleeveorcollarbutton orstud,thebent post B, provided with a notch, b and flattened faces b and I), combined with a spring, 8, and a plate or shoe, A, adapted to engage said notch and to turn around the foot of said 5 post to assume a parallel or a right-angular position relatively tothe post, as shown.

NELS NELSON.
